We demonstrate ultrastrong coupling between highly subwavelength THz resonators and high quality, hBN encapsulated single and bilayer graphene. The presence of gates allows the study of coupling strength as a function of carrier density and , in the case of bilayer, bandgap tuned in the 0-7 THz range.
